[New-bugs-announce] [issue28178] allow to cache_clear(some_key) in lru_cache

[Sébastien de Menten]

New submission from Sébastien de Menten:

It would be useful to be able to clear a single item in the cache of a lru_cache decorated function.

Currently with:

@lru_cache
def foo(i):
  return i*2
foo(1)    # -> add 1 as key in the cache
foo(2)    # -> add 2 as key in the cache
foo.clear_cache() # -> this clears the whole cache
foo.clear_cache(1) # -> this would clear the cache entry for 1
